Personally, I think that are quite a few positive aspects in conservative judaism.
First, two or three decades ago, when a woman wanted to study jewish sources in depth, she could hardly do it within the orthodox world.
Many would go to JTS (the conservatives' seminary in New York), because going to the reformed/liberals would have been irrelevant (or off-limits). For this, there is no doubt that the conservatives provoked some soul-searching among a small fraction of (modern) orthodoxy.
The sorry state of affairs within conservatives is directly related to their decision procedure. Halakhically observant Jews who left their conservative congregation did it not because of the questions that were raised by the conservatives, maybe not even necessarily because of the answers that were given, but mostly because the minimum halakhic requirements in order to reform law were not respected. The dynamics of change became an ideology by itself and everyone had to give in.

If Israel shows greater flexibility, it can still influence the post-nuclear deal agenda ; If Israel digs in its heels, it will increasingly become a liability rather than a strategic asset to the U.S.
